HENRY B. I-IEBERT, OF NEW' YORK, N. Y.

FASTENER FOR THE MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 406,903, dated July 16, 1889.

Application filed March 21, 1889. Serial No. 304,199. (ModeL) To all whom it may concern.-

Be it known that I, HENRY B. IIEBERT, of New York, in the county and State of New York, have invented a certain new and useful Improvementin Sash-Locks, of which the following is a specification.

The object of my improvement is to produee a simple and inexpensive sash -lock, whereby the sashes of a window may be se cured against being opened by means of an instrument inserted between the sashes.

I will describe a sash-lock embodying my improvement in detail, and then point out the novel features in claims.

In the accompanying drawings, Figure l is a top View of that part of the sash-lock which is applied to the top of the inside sash, its cover being removed. In this view I have shown the other part of the sash-lock in dotted outlines. Fig. 2 is a similar view showing the parts in different positions. Fig. 3 is a top view of the part of the sash-lock which is applied to the outer sash. Fig. l is a vertical section of the two parts of the sash-lock, taken on the plane of the dotted line 00 00, Fig. 1; and Fig. 5 is a perspective of the device applied to a window.

Similar letters of reference designate corresponding parts in all the figures.

A designates that part of the sash -lock which is fastened to the top of the inside sash. It is made in the form of a shallow box. It has at the top a cover A, here shown as made in a separate piece and secured in place by screws.

B designates the part of the sash-lock which is secured to the outer sash. It consists of a plate Z), that may be secured by screws or otherwise to the upper surface of the lower rail of the outer sash, and an upward projection I), which has an overhanging head or shoulder L This upper portion of the part ll is, in effect, a hook. Its head or shoulder b extends upwardly, or, in other words, toward the glass of the outer sash.

The boxA of the part that-is secured to the inside sash has an opening a through it about mid way between the sides and extending from the outer edge rear-wardly, or, in other words, inwardly toward the apartment of which the sashes are appurtenances. The opening a is shown as extending through the cover of the box, as well as through the bottom. This opening is wide enough to admit of the upper portion 1) of the part B passin through it.

In the box A are two bolts or dogs C C that are free to slide laterally. They are sub-. stantially L-shaped. Their short limbs or portions c c serve to engage with the under side of the head or shoulder 11 of the part B of the saslrloek. The long portions 0 of the bolts (1" C form shanks, by which the bolts may be adjusted. Guide-rods c are secured to the bolts and extend into the side portions of the box A. In this way the bolts may be guided. The bolts are also shown as guided by fitting at one end against the outer wall of the box A, and, further, by means of pins a. These pins to, in connection with projections (0 formed in the inner side of the outer wall or back of the box A, serve as stops to prevent the bolts or dogs from being moved too far toward each other. Springs D, here shown as of helical form, coiled around the rods 0 and bearing at one end against the bolts and at the other end against the side walls of the box A, serve to shoot the bolts toward each other when they are not restrained from so doing. These bolts when shot outwardly toward each other extend across the opening a in the bottom of the box A and then project beneath the head or shoulder b of the part B. \Vhen they are thus engaged, the sashes will be securely locked together and the plate I) of the part B will extend entirelybeneath the opening, through which access must be had to reach the bolts or dogs, and hence precludes the possibility of tampering with the dogs or bolts by means of an instrument inserted between the sashes.

The under side of the limbs c c of the bolts or dogs I have shown as rounded, and the upper extremity of the upper part I) of the part 13, including the upper part of its head or shoulder IF, I have shown as tapered or rounded upwardly. Either sash which may be opened will when closed cause the dogs or bolts and the upper portion of the part B to contact, and this will result in the spreading of the bolts or dogs automatically, so that the upper portion of the part B may pass between them. After the dogs or bolts shall have passed the head or shoulder, or, conversely, the head or shoulder shall have passed them by the closing of the sash, the dogs or bolts will shoot under the head or projection 11 and the sashes will be secured together.

E E designate levers fulcrumed upon pins e. They are approximately in the shape of elbow-levers. One arm of the lever E bears against the long limb or shank c of the bolt or dog 0 and the corresponding arm of the lever E bears against the long limb or shank c of the bolt or dog 0 The short arms of these levers E E extend toward each other and are inclined near their extremities on the "rear side.

G designates a sliding push-piece guided in the box A. It is shown as having a rod extending through the inner or front Wall of the box A and as provided with a thumb-piece, by which it may be conveniently pushed from within the compartment. It has a tapering rear end, which acts against the inclines on the adjacent arms of the levers E E so as to oscillate the levers in such direction as to effect the movement of the bolts or dogs away from one another for the purpose of releasing the part B of the sash-lock. The levers E E have combined with them stop pins or projections e.

It will be seen that my sash-lock is simple, cheap, and strong, and withal of such construction that it cannot be tampered with by any instrument inserted between the sashes. Its parts will engage automatically, and may at any time be disengaged by simply forcing back the push-piece G.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A sash-lock having in combination two parts, one made in the form of a box furnished with a sliding bolt or dog and having an opening adjacent to the bolt or dog, a guide-rod for the bolt, and a spring on the guide-rod, and the other part having a plate extending beneath said opening and having an upper portion provided with a head or shoulder, substantially as specified.

2. A sash-lock having in combination two parts, one made in the form of a box furnished with a bolt or dog, said box being provided with an opening and furnished with a lever, and a sliding push-piece for operating the lever, and the other part having a plate extending beneath said opening and having an upper portion provided with a head or shoulder, substantially as specified.

3. A sash-lock having in combination two parts, one made in the form of a box furnished with two opposite sliding dogs or bolts and having an opening adjacent to the bolts or dogs, and guide-rods for said bolts or dogs, and the other part having a plate extending beneath said opening and having an upper portion provided with a head or shoulder, sub stantially as specified.

4:. A sash-lock having in combination two parts, one made in the form of a box furnished with two opposite bolts or dogs and provided with an opening and having two levers and a sliding push-piece for operating the levers, and the other part having a plate extending beneath said opening and having an upper portion provided with a head or shoulder, substantially as specified.
